The Land of Water (水の国, Mizu no Kuni) is oriented towards the element of water. Its government leader is the Water Daimyō. It is composed of many islands, with each having its own unique traditions. The country's weather is typically cool and full of mist and lakes. In some places, like the area where Haku grew up, it is very cold and snows quite a bit. Little is currently known about it and it apparently leaves itself out of most political affairs, which is understandable considering that it is composed of vast islands relatively remote from the continent containing the other four major countries. What is known, however, is that the country used to be ravaged by many civil wars, during which clans with kekkei genkai were used extensively, causing many to view them as harbingers of war and death, leading to purges and genocide to the point of parents killing their own children.
Main article: Kirigakure Kirigakure (霧隠れの里, Kirigakure no Sato; Literally meaning "Village Hidden by Mist"), infamously known as the "Village of the Bloody Mist" (血霧の里, Chigiri no Sato), is the shinobi village located in the Land of Water. As one of the Five Great Shinobi Countries, Kirigakure has a Kage as its leader known as the Mizukage. There have been five Mizukage, the current one being Mei Terumī. An unusually high number of missing-nin seem to originate from this village and as such a unique classification of ANBU known as hunter-nin are specifically tasked with eliminating these defectors.
- In matters of land area, the Land of Water is undoubtedly the smallest of the five great nations, not being much larger than some of the largest minor countries.
